Failure to obtain positive MEM tests in either cell-mediated immune conditions in the guinea-pig or in human cancer.

The macrophage electrophoretic mobility test described by Caspary and Field (1971) and modified by Pritchard et al. (1973) was investigated in various models of cell-mediated immune conditions in the guinea-pig and in cancer in man. No positive results were obtained in 92 guinea-pig experiments. Only 17 of 154 experiments on 74 patients gave definite positives in experiments with human cancer and a few positive results were obtained with normal healthy subjects

Rapid identification of Bordetella pertussis pertactin gene variants using LightCycler real-time polymerase chain reaction combined with melting curve analysis and gel electrophoresis.

Recently, eight allelic variants of the pertactin gene (prn1-8) have been characterized in Bordetella pertussis strains isolated in Europe and the United States. It has been suggested that the divergence of the pertactin types of clinical isolates from those of the B. pertussis vaccine strains is a result of vaccine-driven evolution. Sequencing of the prn, which is relatively time-consuming, has so far been the only method for the differentiation of prn types. We have developed a rapid real-time polymerase chain reaction assay suitable for large-scale screening of the prn type of the circulating strains. This method correctly identified the prn type of all tested 41 clinical isolates and two Finnish vaccine strains. The method is simple and reliable and provides an alternative for sequencing in pertussis research

A Randomized Clinical Trial of Attempted Suicide Short Intervention Program versus Crisis Counseling in Preventing Repeat Suicide Attempts : A Two-Year Follow-Up Study

Introduction: The Attempted Suicide Short Intervention Program (ASSIP) is a brief psychotherapeutic intervention, and a pivotal study found it to be remarkably effective in reducing repeat suicide attempts. Objective: To compare the effectiveness of ASSIP to crisis counseling (CC) in a randomized clinical trial (ISRCTN13464512). Methods: Adult patients receiving treatment for a suicide attempt in a Helsinki City general hospital emergency room in 2016-2017 were eligible to participate. We excluded psychotic or likely non-adherent substance-abusing or substance-dependent patients. Eligible patients (n = 239) were randomly allocated to one of two interventions. (a) ASSIP comprised three visits, including a videotaped first visit, a case formulation, and an individualized safety plan, plus letters from the therapist every 3 months for 1 year, and then, every 6 months for the next year. (b) CC typically involved 2-5 (median 3) face-to-face individual sessions. In addition, all participants received their usual treatment. One and 2 years after baseline, information related to participants' suicidal thoughts and attempts, and psychiatric treatment received was collected via telephone and from medical and psychiatric records. Results: Among randomized patients, two-thirds initiated either ASSIP (n = 89) or CC (n = 72), with 73 (82%) completing ASSIP and 58 (81%) CC. The proportion of patients who attempted suicide during the 2-year follow-up did not differ significantly between ASSIP and CC (29.2% [26/89] vs. 35.2% [25/71], OR 0.755 [95% Cl 0.379-1.504]). Conclusions: We found no difference in the effectiveness of the two brief interventions to prevent repeat suicide attempts.Peer reviewe

Lymphocyte recruitment and homing to the liver in primary biliary cirrhosis and primary sclerosing cholangitis

The mechanisms operating in lymphocyte recruitment and homing to liver are reviewed. A literature review was performed on primary biliary cirrhosis (PBC), progressive sclerosing cholangitis (PSC), and homing mechanisms; a total of 130 papers were selected for discussion. Available data suggest that in addition to a specific role for CCL25 in PSC, the CC chemokines CCL21 and CCL28 and the CXC chemokines CXCL9 and CXCL10 are involved in the recruitment of T lymphocytes into the portal tract in PBC and PSC. Once entering the liver, lymphocytes localize to bile duct and retain by the combinatorial or sequential action of CXCL12, CXCL16, CX3CL1, and CCL28 and possibly CXCL9 and CXCL10. The relative importance of these chemokines in the recruitment or the retention of lymphocytes around the bile ducts remains unclear. The available data remain limited but underscore the importance of recruitment and homing
